Title
net: hns3: fix kernel crash when 1588 is received on HIP08 devices
Summary
In the Linux kernel, the following vulnerability has been resolved: net: hns3: fix kernel crash when 1588 is received on HIP08 devices The HIP08 devices does not register the ptp devices, so the hdev->ptp is NULL, but the hardware can receive 1588 messages, and set the HNS3_RXD_TS_VLD_B bit, so, if match this case, the access of hdev->ptp->flags will cause a kernel crash: [ 5888.946472] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000018 [ 5888.946475] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000018 ...
